Appumion 'tied December 8,1904. semi No. 236.035..

Be it known that I, MARVIN MEAD, a citizen ofthe United States, residing at Pueblo, in the county of Pueblo andthe State of Colorado,

have invented a new and useful Improvement in Hay-Stacker's, of which the following is a specification. y

This invention relates to hay stackers and loaders to be used in the field, where hay is delivered to it by means of a bull-rake'or similar device. l

The object 0I' the device is a stacker adapted for use at the -end ofa stack delivering the hay in the center with the greatest length of the load delivered transverseto the longitudinal line of the stack.

A further object of the invention is to provide a stacker that will convey the hay from the ground and drop it at anydesired point lalong the longitudinal center of the stack and transverse to said axial line, so that'iily a small portion of the hay will be required' to be moved by hand after having beendumped.

A still further object is a stacker which will commence delivering hay from a comparatively low point and which can be elevated as the stack is built up, thus avoiding the ex' penditure of time and labor in carrying the hay to a greater height than is absolutely necessary.

My invention also consists in the 'novel features of construction and combination of parts hereinafter described, pointed out in the claims, and sho-wn in the accompanying 'drawings, in which f Figure l is a side elevation, the'carriage being shown in full lines in position to be loaded and in ascending and dumping positions in dotted lines. Fig. '2 is a' detail view-ol the carriage,parts being in section. Fig. 3 isa plan view of the track. Fig. 4 is a plan view, enlarged, of the carriage.4

In constructing my stacker I employ s uitable base or bed rails A, upon which rest triangular frame's A'. I l are parallel to each other, and in Fig. l but one rail and frameare shown. vide a movablev truss. track-section B, which is provided with pivoted supporting-legs C. At their lower ends the legs C carry guide- Y brackets D, which slide on one member ofthe lframes A' and are provided with a'roller D',

traveling'on its respective frame, as most clearly shown in Fignl.4 These legs C supportv the track-section B in an inclined position, and the degree of inclination can be va- 'I'rom the rails.

These vframes and rails I further proried by means of a cableE, wound upon a suitagble drum provided with aratchet E and pawl E2. l A cable is secured to each 0I1 the legs land may run to separate drums independently operated by cranlI-handles E3, or both cables may extendto one drum, so that both can be j..wound or u'nwound from one side of the frame by turning the handle E3.

In practice I place ratchets E' 4and handles E3 on each side of the device, so that two men can engage in the work of shifting the inclination of the track. It will be obvious that as the cablesv E are wound upon the drum or drums the supporting-legs C will .be drawn up the incline ofthe frames A and the delivering endof the track B elevated.

The track-section B comprises rails B and cross-ties B2. The ties B2, with the exception of the uppermost onev andl the lowest, carry brackets-B2, in which slide longitudinally with respect to the ties angled rods B2. The angled portion B5 of these rods curves over one,side and under the tiesB2, so that they can be reached `from below the track by the hand or the tines of a pitchfork in order to shift the position of the rods` sliding them to and away On the uppermost tie B2 are arranged adjacent the rails B' bails or staples B6, which serve the same purpose as the rods B2, but which are not adjustable.- The object ofthe rods B4L and bails B, as will more-fully appear hereinafter, is to trip the movable carriage'and dump the load.

The carriage F comprises two racks in the I'orm of rakes, F and F2., the tines forming therack F' being longer than those forming the rack F2, the former supporting the hay and the latter serving as a back to hold the load in place. The carriage is provided with wheels G, and I prefer to iange the track-rails B', though smooth rails and ianged wheels could be employed, if desired. The wheels `Vare mounted on short stub-axles Hand turn loosely on thesame, the vcarriage F being practically pivoted between the wheels G.

vBifurcated brackets H' extend forwardly from each axle H and at their forwardv ends have an angled catch H2, which is engaged by a .slidable hook member J, one of which is arranged on each side of the carriage. The free ends of the bracketsH' are connected to cables K, which when taut hold the brackets parallel to the track-rails B', and when the hook member .I is in engagement with the catch H2.' the carriage F is prevented from turning upon its pivotal points. Aspring J', arranged ad-v jacent each hook member J, normally holds the hook in engagement with the catch H2. The lower end of the hook member J is curved downwardly, but will pass freely over the ties B2.

The rods B2, heretofore mentioned, when moved toward the rails B' will lie in the path of the lower curved ends of tbe hook members J, which curved portions J2 will engage the rods and check the forward movement of the carriage, and the hook will also be withdrawn from engagement with the catch H2 on each side of the carriage, and the load will be dumped automatically by reason of its weight,

the carriage swinging back into its normal position when relieved of its load.

In order to move the carriage up the inclined track, pulleys L, L, and L2 are suitably arranged on the track-section in pairs, one of each pair on a side, and cables K are connected to the free ends of the brackets H of the rackFand carried over the said pulleys. Any suitable power and form of device, such as a drum rotated by hand or horse power, may be employed to apply the pull on the cables K necessary to draw the carriage up the track.

-In operating the device the stacker is placed at the end of the stack and the delivery or forward end of the track elevated to the desired height. The carriage F rests at the lower end of the track, the rack F' being in ahorizontal position and upon the ground. The load is delivered upon the rack F2, and on applying power to the cables K the rst movement of the carriage will be upon its pivotal points, the rack F2 lifting the free ends of its tines into a position at an angle to the track B. This movement is of importance, as otherwise in case of bodily movement of the carriage up the track at the first pull on the cables the rack F' would be drawn from under its load and much of the hay would slip from the rack. When the carriage has assumed the first position, (shown in dotted lines in Fig. 1,) it moves up the rack until tripped by the portions J2 of the hook members J coming in contact with the rods B4 or, if the load is to be dumped from the end of the track, with the staples B6. The ties B2 are spaced sulficiently far apart to permit the load to be dumped between any two of them, and as the stack rises in height the track can be elevated by means of the handles E3 and cables E, as previously stated. The stacker being set at the end of .the stack to be formed, the track extends over the longitudinal center or axial line of the stack, and hay can be deposited upon the stack throughout its entire length by adjusting the various tripping-rods B. When the stack is to be topped, the carriage is tripped by the bails or staples B, and instead of dumping its load the rack F2 will rest upon the stack, and the hay can be spread therefrom by forks upon the top, employing the last load to cap the stack.

To those familiar with the stacking of hay, straw, &c., the advantages arising from being able to deposit the load along the longitudinal line of the stack and also of conveying it to the highest point of travel of the carriage before tripping, when desired, will be obvious.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A hay-stacker comprising an inclined track, adjustable tripper-rods carried by the track, a carriage movable on the track, and mechanism carried by the carriage and adapted to trip the same when in engagement with the rods.

2. A hay-stacker comprising an inclined track comprising rails and cross-ties,a wheeled carriage adapted to travel on the rails, tripper-rods carried by the ties and adjustable with respect to the rails, locking mechanism carried by the carriage adapted to be unlocked by engagement with the tripper-rods, and means for varying the inclination of the track-section.

3. A hay-stacker comprising an adjustable track-section, a carriage comprising liivotallymounted hay-racks, means for moving the carriage on the track, means for locking the racks against dumping, tripper-rods carried by the track-section, said rods being adjustable and adapted to unlock the racks when engaged by the locking mechanism, and bails carried by the delivery end of the track-section adapted to trip the said carriage.

4. A hay-stacker comprising a track-section, a wheeled carriage adapted to'travel on the track and comprising racks arranged at anangle to each other and pivotally mounted between the said wheels, means carried by the carriage for normally locking the racks againstrotation on their pivot-points, and adjustable tripper-rods carried by the track-scetion adapted to unlock the said racks and permit dumping of a load.
